I use fediverse more than Bluesky, but my fediverse account can also be followed on Bluesky via Bridgy Fed, so I think you might want to follow it: @hongminhee.hollo.social.ap.brid.gy.

LogTape 2.4.0 is out. It adds opt-in source locations for development logging, inspectLogger() to explain why a record doesn't reach a sink, drain() for pending sink output, and completionLevel for Express, Hono, Koa, and Elysia.

JSConf JP 2026で登壇することになりました。11月22日(日)、東京のベルサール神田にて。 タイトルは「Oseo：SBCLスタイルのJavaScript/TypeScript AOTコンパイラ」。SBCLやChez Schemeのように、動的型付き言語のまま全体を事前にネイティブコードへコンパイルするJavaScriptエンジンの話をします。型注釈は最適化のヒントとして使うだけで、決して鵜呑みにしない設計です。 発表は日本語、14:10からトラックC。下記のリンクをご参照ください。

Optique 1.3.0 is out. Optique is a type-safe combinatorial CLI parser for TypeScript. Dependency sources now resolve regardless of parser declaration order. Two new packages add an OS keychain fallback and CLI testing tools.

I've released Upyo 0.6.0, a cross-runtime email library for JavaScript and TypeScript. It adds MIME composition, streaming SMTP attachments, calendar invitations, and Maileroo and Mailtrap support.

don't have a template i can show unfortunately but i can def recommend optique.dev

It is an honour to have been interviewed on behalf of the DrFed team for @apc.org (Association for Progressive Communications)'s Building a Free Internet of the Future series.

LogTape 2.3.0 is out: withConfig() for scoped, temporary logging policies, a failure-only test log reporter (with Node.js/Deno/Bun/Vitest packages), a GraphQL Yoga adapter, and Sentry routing for logs vs. breadcrumbs by level.

Optique, a type-safe combinatorial CLI parser for TypeScript, just shipped 1.2.0. Chainable modifiers (.map().withDefault()), a deferredValue() for fallbacks that resolve inside your handler, four new packages, and a redesigned site.

This week I spoke at @localfirstconf.com in Berlin. A lot of the audience had Claude Code open, and still applauded every time when a speaker would say something LLM-critical on stage. I feel the same. So I wrote it down: www.theocharis.dev/blog/llm-cri...

Requested a #CVE ID via a #GitHub Security Advisory on June 27, still nothing almost two weeks later. Docs say up to three days normally. Anyone else seeing longer waits from the GitHub CNA lately, or is this just me? #FOSS #InfoSec #GHSA

Oh dear lord, I knew it was bad, but didn't know it was this bad: hackers.pub/@fedify/2026... (I've mostly just contributed to activitypub projects that already existed, so didn't usually need to experience these specific pains)

Upyo 0.5.0: a cross-runtime email library for #JavaScript and #TypeScript with one transport API across SMTP, JMAP, Mailgun, SES, Resend, and Plunk. This release adds structured delivery errors, automatic retries, a Lettermint transport, and OAuth 2.0 for SMTP.

Good read. Personally, I lean towards percent encoding, but there are a lot of good arguments to be made for and against it.

one api for every email provider so you stop rewriting send code, yes please

#LogTape 2.2.0 is out! New: lint rules for ESLint, Oxlint & Deno Lint that catch common logging mistakes, testing utilities with assertion helpers, request context for HTTP integrations in one option, and seven core performance improvements. #JavaScript #TypeScript #Node #NodeJS #Deno #Bun #logging

Optique 1.1.0 is out: a new package for file-based command modules, five new value parsers (fileSize, color, semVer, json, keyValue), seq() for ordered grammars, and negatableFlag() for --color/--no-color. #TypeScript #CLI

國漢文을 한글로 바꿔주는 소프트웨어인 Gukhanmun 0.2.0이 릴리스되었습니다. 《標準國語大辭典》과 더불어 《우리말샘》 데이터를 包含하게 되었고, 各種 코너 케이스를 더 잘 다루게 되었습니다. 또한, 國漢文 原文에 括弧로 한글 倂記가 되어 있을 境遇, 이를 結果文에서도 反映하여 漢字 倂記가 되거나 한글 讀音이 달리게 되었습니다. 그 밖에도 여러 改善 事項들이 있으니, 仔細한 內容은 릴리스 노트를 參考하시기 바랍니다.

If it's simple parseArgs, if it's more complex optique by @hongminhee.org

What do you use these days to build simple CLI tools in Node? Is sade still the go-to, or do you go plain node:util parseArgs() and some manual wrangling? I have a CLI tool that has 3-4 subcommands with 1-2 options each. Wonder how many dependecies I'm willing to accept here. Maybe @e18e.dev knows?

LogTape 2.1.0 is out. Main additions: a throttling filter for suppressing log floods, a built-in logfmt formatter, timezone control for timestamps, and HMAC pseudonymization in @logtape/redaction.

Show GN: 만진법 프로젝트: 한·중·일 언어권을 위한 수 표기 제안 한국어·중국어·일본어는 만(萬) 단위로 수를 읽는데, 아라비아 숫자는 천 단위로 쉼표를 찍습니다. 1,234,567,890을 보고 “십이억 삼천사백오십육만 칠천팔백구십”을 바로 읽어내려면 매번 머릿속에서 자릿수를 다시 세야 합니다. 그러므로, 만 단위 구분자로 밑줄( _ )을 쓰자고 제안합니다....

East Asian languages count in ten-thousands, not thousands. So why do we still group digits by three? A proposal: 1,234,567,890 → 12_3456_7890.

1,234,567,890用中文读是「十二亿三千四百五十六万七千八百九十」，但逗号却打在千位上。我们提议用万进制表记：12_3456_7890。

1,234,567,890用中文讀是「十二億三千四百五十六萬七千八百九十」，但逗號卻打在千位上。我們提議用萬進制表記：12_3456_7890。

1,234,567,890を日本語で読むと「十二億三千四百五十六万七千八百九十」。なのにカンマは千の位。万進法の表記を提案します：12_3456_7890。

1,234,567,890—韓國語로는 「十二億 三千四百五十六萬 七千八百九十」인데, 쉼標는 왜 千 單位에 있을까요? 萬進法 表記를 提案합니다: 12_3456_7890.
